IS 206:1986 is the Indian Standard (BIS) for door bolts (aldrop type). This standard specifies the requirements for materials, dimensions, manufacture, and finish of aldrop type door bolts used in building construction. Architects and procurement engineers use this code to ensure standardized quality and proper functioning of door hardware fittings.
Specifies materials, dimensions, and finishes for Aldrop type door bolts.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Classification Method | By nominal length (e.g., 200, 250, 300 mm). | By 8-digit code defining Category of use, Durability, Door mass, Corrosion resistance, etc. | BS EN 12051:2000 |
| Material Specification | Mild steel conforming to IS 226. | Not specified. Any material that meets performance requirements is acceptable. | BS EN 12051:2000 |
| Durability Requirement | Not specified in terms of operational cycles. | Performance graded by number of test cycles (e.g., 25,000 or 50,000 cycles). | BS EN 12051:2000 |
| Static Load Resistance (Security) | Not defined by a force value; strength is implied by prescribed material thickness. | Must resist a defined static load applied to the bolt (e.g., 1000 N for Grade 4). | BS EN 12051:2000 |
| Corrosion Resistance Requirement | Prescribes a protective coating (e.g., zinc plating per IS 1573, black japanning). | Requires passing a neutral salt spray (NSS) test for a specified duration (e.g., 96 hours for Grade 3). | BS EN 12051:2000 |
| Bolt Diameter (for 300 mm bolt) | 12.0 mm | Not specified; dimension is at the discretion of the manufacturer to meet performance tests. | ANSI/BHMA A156.16-2018 |
